NTRU Post Quantum Cryptography

Why risk waiting for an attack? NTRU is used by organizations interested in maintaining their current cryptographic choices but wanting to future-proof against quantum threats.

Quantum-Safe, Standardized Crypto

Now is the time to address the elephant in the server room. Both RSA and ECC are vulnerable to quantum computing attacks and the availability of practical quantum computers is approaching faster than previously believed. Organizations interested in maintaining their current embedded cryptographic choices but want to immediately future-proof against quantum attacks are embracing our Quantum Safe Hybrid (QSH) approach.

NTRU is a lattice-based public key cryptosystem and the most thoroughly researched and widely implemented alternative to RSA and ECC. It supports encryption, decryption, and signing. Not only faster and smaller than RSA and ECC, NTRU is the leading choice for organizations recognizing the need to protect themselves against the looming threat of Quantum Computing attacks. NTRU is an IEEE 1363.1 and X9.98 financial services standard.

Advantages of NTRU Cryptography

Ideal for all environments, but particularly well suited for embedded and mobile devices where code size is a major limitation

Significantly reduces server utilization for large-scale deployments

HUGE PERFORMANCE INCREASES

Highest performing public key cryptography

Decryption is more than 92x faster than RSA decryption at an equivalent security level

NTRU is nearly 60% faster than RSA at encryption and TLS with a 370 times improvement in key generation time

Encryption and decryption are faster than the best-performing ECC algorithms at equivalent security levels.

QUANTUM-SAFE HYBRID

Accomplishes TLS authentication and key negotiation by combining today’s classic cryptography with NTRU quantum-safe cryptography, ensuring the best of both worlds

Parallel implementation allows for benefits of NTRU on top of existing crypto infrastructure with a negligible performance penalty.

PREVENTS DATA HARVEST ATTACKS

Protects information that needs to remain secret for many years by keeping encrypted traffic from being recorded and warehoused today and decrypted when quantum computers are available

Ideal for systems that have long lifecycles or can’t be updated easily
